Algae transplant could protect coral reefs threatened by warming seas

Heat-resistant algae made in a lab seems to protect coral from bleaching. It could help to save reefs if we fail to tackle global warming fast enough Source: https://www.newscientist.com/article/2243348-algae-transplant-could-protect-coral-reefs-threatened-by-warming-seas/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Glowing Blue Waves Lighting Up SoCal Coastline Roll Into the South Bay

Crashing waves emitting a flash of neon blue have lit up darkened stretches of Southern California’s coastline this month, most recently making an appearance in the South Bay. From a report: The sporadic phenomenon — sometimes called sea sparkle — is something scientists have been studying for 120 years. It’s associated with a red tide, or an algae bloom, made up…

Will sea otters return to San Francisco Bay?

A new study shows that, if they can be returned to San Francisco Bay, California’s southern sea otter population can be tripled. There are now only about 3,000 of the otters left. But, first, they’ll need some help getting past the great white sharks. Source: https://earthsky.org/earth/southern-sea-otters-reintroduction-san-francisco-bay…

Can We Save Coral Reefs Using Underwater Loudspeakers?

“The desperate search for ways to help the world’s coral reefs rebound from the devastating effects of climate change has given rise to some radical solutions,” reports the Washington Post. There’s coral “nurseries” in the Caribbean, while Hawaiian scientists are trying to breed a new and more resilient type of coral. But at least one team focused on the herbivorous fish…

Algal blooms are getting worse in lakes worldwide

‘Personal Carbon Sequestration’ Device Uses Algae To Remove CO2 From the Air

An anonymous reader quotes a report from Fast Company: In the future, your office might have an extra appliance next to the copy machine and the refrigerator: an algae bioreactor. Designed to fit inside offices and eventually sit on the rooftops throughout cities, it can capture as much carbon from the atmosphere as an acre of trees. And there’s an initial…

Could microbes be affecting Venus’ climate?

Unusual dark patches in Venus’ atmosphere – called “unknown absorbers” – play a key role in the planet’s climate and albedo, according to a new study. But what are they? That’s still a mystery. Source: https://earthsky.org/space/could-microbes-be-affecting-venus-climate…
